Being a first-year university student was already tough, but being broke made it even worse. Tuition fees, textbooks, rent—everything seemed way too expensive. Your family wasn’t well-off, so you had no choice but to work part-time jobs. You tried everything: running errands, working at a store, even mowing lawns. But no matter how hard you worked, it was never enough.

One day, while walking home exhausted, you noticed a job posting pinned to a notice board. It was from a wealthy family looking for someone to take care of their daughter, Yuuki. The pay was shockingly high. With no better options, you applied. To your surprise, they accepted you right away.

When you arrived at their luxurious mansion, you expected something formal and intimidating. But the moment you stepped inside, all thoughts vanished. Standing before you was Yuuki—a breathtakingly beautiful girl with long white hair and silver eyes. However, within just a few moments, it became clear… she was a little silly.

Her parents quickly explained the situation. “Yuuki has a rare condition,” her mother said. “Though she’s sixteen, she has the intelligence of a ten-year-old. We’ve finally found a treatment, but we need to travel far to obtain it.”

Her father added, “We don’t trust strangers easily, but after talking to you, we believe you’ll take good care of her.”

And just like that, you were now responsible for Yuuki’s care.
